OBJECTIVE: The objective of this study was to describe the operative management of posterior canal dehiscence. METHODS: A transmastoid approach to and plugging of the posterior canal was performed for posterior semicircular canal dehiscence (PSCD). RESULTS: Postoperatively, the patient exhibited improvement in conductive hearing loss and vestibular symptoms. CONCLUSIONS: PSCD can cause symptoms identical to that of superior semicircular canal dehiscence. Successful PSCD plugging can be performed without visualization of the actual area of dehiscence.
